NATIONAL TECHNICAL REGULATION
ON PRODUCTS AND GOODS OF BUILDING MATERIALS

Part 1.

GENERAL

1.1. Scope of regulation

This Regulation defines technical requirements for products and goods of building materials as stated in Part 2 (hereinafter referred to as products and goods of building materials). Such products and goods are manufactured domestically, imported and sold in the Vietnamese market.

This Regulation does not govern products and goods of building materials imported as product sample, prototype, exhibition goods, temporary imports for re-export and goods in transit.

1.2. Regulated entities

1.2.1. Organizations and individuals that manufacture or import products and goods of building materials.

1.2.2. Authorities that conduct state management of the quality of relevant products and goods.

1.2.3. Organizations that are designated to assess the conformity of products and goods of building materials.

1.3. Terminology

In this Regulation, the following words and phrases are construed as follows:

1.3.1. Cement is a hydraulic binder in the form of a fine powder that, when mixed with water, forms a viscous paste hardening into stone in air and water through physicochemical reactions.

1.3.2. Cement clinkers are hydraulic binders that contain phases (minerals) and are made by sintering or by melting of a blend of certain ingredients (aggregates).

1.3.3. Glass products for construction sector are used and installed in buildings.

1.3.4. Cement admixtures are natural or artificial materials, in the form of a fine powder or liquid, blended into cement during its production for technological enhancement and for attainment of quality norms required without marring characteristics of cement.

1.3.5. Admixtures for concrete and mortar are added during the production of concrete and mortar to attain quality norms required without causing detrimental effects on properties of cured concrete blend, concrete or mortar and of reinforcing steel inside concrete. Admixtures for concrete and mortar are minerals or chemicals.

1.3.6. Mineral admixtures are natural or manmade inorganic materials fine-crushed and added during the process of blending to improve particle size distribution and composition of cement stone, concrete and mortar.

1.3.7. Chemical admixtures are added in a certain amount (not more than 5% by cement weight) before or during the process of blending in order to alter certain properties of cured cement blend, cement and mortar.

1.3.8. Building materials containing inorganic or synthetic organic fibers; and wood-based products refer to sheet products composed of inorganic fiber and/or synthetic organic fiber; artificial wood boards such as MDF or particleboard; manmade 3-layer floorboard with surface layer, middle layer and bottom layer chiseled in proper sizes; aluminum products and aluminum alloy profiles and unplasticized polyvinyl chloride pipes (PVC-U). Such products are used and installed in buildings.

1.3.9. Emulsion paint for walls is dispersion paint or water-soluble paint. Epoxy paint protects steel and metal structure, etc. Alkyd paint refers to alkyd-based paints modified by naturally drying herbal oil. Waterproofing materials are bituminous waterproofing membranes or polymer-cement-based coating liquid or waterstops made from PVC or rubber, structural silicone sealant.

1.3.10. Volatile organic compounds are organic chemicals in solid and/or liquid form, which can evaporate naturally under atmospheric pressure at ordinary temperature. They may pose risks of harmful effects on human and environment.

Volatile organic compounds include methylene chloride (dichloromethane);

1,1,1-trichloroethane (methyl chloroform); parachlorobenzotrifluoride (PCBTF); cyclic, branched, or linear completely methylated siloxanes; acetone; perchloroethylene (tetrachloroethylene); methyl acetate; t-butyl acetate with boiling point not exceeding 250oC at the pressure of 101.3 kPa.

1.3.11 Tiles and stone slabs are natural or manmade sheets of brick or stone whose edges or surface is finished or unfinished. These products serve purposes of cladding or paving for buildings.

1.3.12. Ceramic sanitary ware products refer to ceramic products used for sanitary purposes.

1.3.13. Aggregates are loose materials of natural or artificial origin with certain granular component. When mixed with cement and water, they form concrete or mortar. Grain size determines small and coarse aggregates.

1.3.14. Small aggregate is composed of aggregate particles whose size ranges from 0.14 mm to 5 mm. Small aggregate may be natural sand, crushed sand and their blend.

Natural sand is composed of small weathered particles of natural rocks. Natural sand refers to as sand.

1.3.21. Lightweight concrete - foam concrete or non-autoclaved air-cured aerated concrete made from Portland cement, water, foaming agent or air with or without fine aggregate, active mineral and chemical admixtures.

1.3.22. Lightweight concrete - autoclaved aerated concrete (AAC) brick, made from quartz sand, lime, fine-crushed gypsum, cement and water through aeration.

1.3.23. Batch combines one type of products or goods of building materials having similar specifications and produced at once through one technology line.

1.3.24. Lot combines one type of products or goods of building materials, in a defined quantity, which have similar label content, are produced or imported by one entity at one location and are distributed and sold in the market.

1.3.25. Potentially unsafe products and goods of building materials pose latent risks of adverse effects on human, animal, plant, property and environment despite their being transported, stored and used sensibly and properly.

1.4. General regulation

1.4.1. Products and goods of building materials must remain safe while being transported, stored and used.

1.4.2. Producers and importers must declare types of products and goods of building materials precisely as per the product list in Part 2.

However, the result of the test for compressive strength of samples after 7 days is not required.

A batch of products shall only be announced to have attained conformity and be eligible for use and sale in the market upon the compliance of all test values, including results of tests after 7 days, with the requirements.

3.1.5. Procedures for certification and announcement of conformity and marking shall be governed by regulations on certification and announcement of conformity and relevant laws.
